14 SEER only in R410a??

[nodule]

Are the Amana and Heil 14 SEER A/C units only available in R410a?

[BaldLoonie]

If you mean the ones with a 4 in the model #, it appears so.

But with Heil and I think Amana is the same way but their website is still down, you can get 14 SEER out of the 13 SEER unit with variable speed blower.

Get used to it, R22 is going away :(

I thought ICP was going to come out with a 14Seer in R22 with direct drive AHU sometimes this year...because they do not have a R22 variable speed AHU in the new line (w/o changing the x-valve)...........:(

One contractor told me the R410 systems run at a much higher pressure and
thus the unit will break down more and not last as long as a R22 unit. Any
truth to that at all?

[hotntired]

No truth to that whatsoever. Most manufacturers report fewer failures in 410-a products. Installers must be familiar with the installation process and adhere to the practices of: good vacuums, nitrogen bleeds and most importantly.....know how to correctly charge a system.


There is nothing to fear from a 410-a system that you shouldn't be fearing from a so-so installer with r-22.

R410 systems are designed to operate on that pressure and there won't be any more breakdowns related to pressure than r22. The problems or breakdowns will be mistakes made installing the systems such as- not flushing the old oil out of the refrig lines or replacing the refrig lines, making sure soft solder was not used in the previous installation, keeping a very dry installation. The oil in r410 systems will not give up any moisture it absorbs by evacuating, so if a leak has occured in the system and it continued to run in a vacume absorbing all that moisture, the oil must be replaced in the compressor as well as repair the leak. Driers won't help either. I would say incorrect installation and repair proceedures will be the real problem, not the system.
I have a few r410 systems out there and have had no problems yet.

I think what this suggests is that there will be a period of time for the majority of install techs to do the installs correctly to a R410A standard, and for consumers to become familiar with the increased costs that will be passed along for the retraining and retooling of the HVAC industry.

Remember, there is no such thing as "government money," and unfunded mandates like R410A are ALWAYS passed along to the last user in line. That user is ALWAYS the consumer.

All the money that government has comes from just one place: you and me.

A 410-A compressor is actullay less likely to break down. The refrigerant and P.O.E. oil mixes better together than the r-22 and mineral oil does. Therefore, you get better oil return and lubrication due to the miscibility of the P.O.E and 410A.

After 10 years of selling and installing the 410-a sytems that Carrier introduced to the market, I find it somewhat funny to be hearing all negative comments about it that we went through back in 98'.

I think most manufactureres had 410-a as an option at least 5 years ago. Knowing where the trend was going at that time I wonder why so many are still dragging their feet when it comes to 410-a. It's time to embrace the glory that is "PURON" and start feeling the love from mother earth.:D

Higher pressure yes,more breakdowns,NO!

I agree

[DE J-man04]

seems to me you talking to a contractor who dosnt know anything about R-410a remember R-22 wont be here much loner so if you get a 22 system in a few years be ready to pay high prices if you have a leak

Unless you have a bottle of 22 sitting in your garage, wink, wink, just for that reason.:D

[kundesc]

yea for some reason i still have 50lb bottle full of R-12.
